What current to charge the battery to get the highest efficiency

Many car owners are faced first with the problem of discharge of rechargeable automotive batteries and their own decisions to charge it, ask myself the following question: "What current to charge the battery?". In order to carry out this plan, you first need to have start-charger or a charger that allows you to convert the current supplied from the usual outlets at 220V, the current which has a much lower voltage – 15V. Measuring voltage at 15V are considered optimal in order to make high-quality charge the battery without breaking the system.

Responding to a question about what current to charge the battery, it is first necessary to determine the choice of method of battery charge.

• Method DC. With this approach, you need to constantly adjust the current, which is supplied to the charge. For example, let's calculate to find out what current to charge the battery 60 A/h capacity. The strength of the current is calculated from the ratio of 1:10 to the battery capacity. In this example it is equal to 6 Amperes. Not allowed to submit current above 6 Amps, as it can harm the system battery. A smaller force is allowed to apply to the battery 60 A/h, but in this case, the time on a full charge increases as increases, and the efficiency of the work performed.

How to determine a full charge? As soon as the battery is charged, it will begin to give off gas. This is a sure sign that the battery is fully charged and ready for use. Another sign of full charge – is the stability of the voltages for an hour or more. Improving the efficiency of the charge will be the higher, the more reduced current at end of charge. To do this, before the battery is fully charged, you should gradually reduce the strength of the current (at the index of 14.4 V is supplied current at 3 ampere). Such exposure increases the charging voltage.

• Constant voltage Method. The tension adjustment is not needed, but the question of what current to charge the battery, remains. The battery is connected to a continuous voltage, while current mechanical size is equal to the capacity current in the battery and timing the charge is reduced and may fall to the level of "0". This technique is used largely for the batteries which have a voltage of 12V. In this case the voltage used when charging has records up to 15V.

When the battery is full, as a rule, does not emit excess gas, since the charge amounts to 95%. Knowing what current to charge a car battery, it's important to choose this method effective regulatory charger.

• There is another method – egalitarian, which is used when the battery is charged at 95% and it needs to sum to 100%. To the question about what current to recharge the battery in this case, the answer is current, equal to the following calculation. Current equal to 3% of the battery capacity. This not only achieves 100% charge, but with the density of electrolyte in all banks of AKB.
